{"id":"GHSA-f4v7-3mww-9gc2","summary":"Keycloak allows unrestricted admin use of system and environment variables","details":"A security vulnerability has been identified that allows admin users to access sensitive server environment variables and system properties through user-configurable URLs. Specifically, when configuring backchannel logout URLs or admin URLs, admin users can include placeholders like ${env.VARNAME} or ${PROPNAME}. The server replaces these placeholders with the actual values of environment variables or system properties during URL processing.\n\n","aliases":["CVE-2024-11736"],"modified":"2026-09-10T03:50:21.922687287Z","published":"2025-01-13T16:58:08Z","database_specific":{"cwe_ids":["CWE-526"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2025-01-13T16:58:08Z","nvd_published_at":"2025-01-14T09:15:20Z"},"references":[{"type":"WEB","url":"https://github.com/keycloak/keycloak/security/advisories/GHSA-f4v7-3mww-9gc2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-11736"},{"type":"WEB","url":"https://github.com/keycloak/keycloak/commit/7a76858fe4aa39a39fb6b86dd3d2c113d9c59854"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:0299"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2025:0300"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2024-11736"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2328850"},{"type":"PACKAGE","url":"https://github.com/keycloak/keycloak"}],"affected":[{"package":{"name":"org.keycloak:keycloak-quarkus-server","ecosystem":"Maven","purl":"pkg:maven/org.keycloak/keycloak-quarkus-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.0.8"}]}],"versions":["12.0.0","12.0.1","12.0.2","12.0.3","12.0.4","13.0.0","13.0.1","14.0.0","15.0.0","15.0.1","15.0.2","15.1.0","15.1.1","16.0.0","16.1.0","16.1.1","17.0.0","17.0.1","18.0.0","18.0.1","18.0.2","19.0.0","19.0.1","19.0.2","19.0.3","20.0.0","20.0.1","20.0.2","20.0.3","20.0.4","20.0.5","21.0.0","21.0.1","21.0.2","21.1.0","21.1.1","21.1.2","22.0.0","22.0.1","22.0.2","22.0.3","22.0.4","22.0.5","23.0.0","23.0.1","23.0.2","23.0.3","23.0.4","23.0.5","23.0.6","23.0.7","24.0.0","24.0.1","24.0.2","24.0.3","24.0.4","24.0.5","25.0.0","25.0.1","25.0.2","25.0.3","25.0.4","25.0.5","25.0.6","26.0.0","26.0.1","26.0.2","26.0.4","26.0.5","26.0.6","26.0.7"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/01/GHSA-f4v7-3mww-9gc2/GHSA-f4v7-3mww-9gc2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"}]}
